Xavier,
SEM worked great in Chile. I used it with two D850s in silent photography mode and I'm really happy with the results. The only problem was operator error. I wanted to obtain a rapid series of images just before C2 and after C3 to create a Baily's Beads mosaic, similar to the one at the bottom of the SEM website. My strategy was to use the TAKEBST command to capture 70 frames just before C2 and after C3. Unfortunately, I left a 4 sec gap in the commands to allow for the camera buffer to write to the XQD card. I didn't realize that, in 4 seconds, Baily's Beads changes dramatically! Consequently, I missed my mosaic, but I now know how to use the simulations better and will get my mosaic in 2020 (hopefully).
Thanks for the support and the software!
Steve
PS, I've posted a couple images on my FB page if anyone wants to check them out.
